Exam 9: Photosynthesis and Cellular Respiration

The number and arrangement of membranes within a chloroplast are important to the chloroplast's functions. How would the absence of these membranes affect the manufacture of ATP within a chloroplast?

Although ____________________ has less energy than other energy carriers, it is more versatile because it can be used in a larger variety of chemical reactions.

The enzyme rubisco is important to the process of

Not all visible light supports photosynthesis; only those wavelengths colored ____________________ and ____________________ can excite the chlorophyll molecules in an antenna complex.

Stomata admit CO₂ but also facilitate the loss of water; plants must regulate their stomata carefully or risk dehydration. A reasonable hypothesis associated with the global increase in atmospheric CO₂ is that plants will

The Krebs cycle takes place in the

Cellular respiration is, essentially, the opposite of photosynthesis.

World-class sprinters typically do not breathe during the 9+ seconds needed to complete 100 meters. What does this suggest about their energy production?

The energy carriers NADPH and NADH differ structurally. Functionally they

In mitochondria, the energy released by electrons as they move through the electron transport chain is used to transport

The light reactions in photosynthesis result in three output products: molecular oxygen, ATP, and ____________________.

____________________ reactions break down and gradually oxidize food molecules to produce energy.

During photosynthesis, energized electrons flow from

Which of the following molecules carries electrons that will be used to reduce other molecules in an electron transport chain?

Which of the following statements comparing photosynthesis and cellular respiration is accurate?

Glycolysis is an anaerobic process, indicating that the glycolytic reactions

A funnel is used to channel substances collected over a wide area into a narrow-necked container. A funnel might be a good analogy for the

Several plant pigments have significant antioxidant qualities and can protect a cell from the damage inflicted on its biomolecules by free radicals.

ATP synthase is a protein involved in the redox reactions of the electron transport chain.

The energy needed to produce the flash of a firefly originally came from sunlight.
